What are the dangers of green blind bugs to young grape leaves? What are the best ways to prevent an

After the green blind bug bites, the leaves have red spots and shrunk, and the scars are left after biting the fruit, and there is no commerciality directly), in the absence of prevention in place, it has brought serious economic losses to many fruit farmers.

I now usually arrange to plant signal vegetables to observe insects, and plant a few rape or peas every five or six meters or ten meters or eight meters. Grapes are planted before bud break. Comprehensive soil disinfection treatment.

7-9 holes per square meter are drilled around the vine stem 25 cm from the base of the stem, the hole is 15 cm deep, 8 grams of carbon disulfide are injected into each hole in spring, and 5 grams of liquid medicine are injected into each hole in summer to disinfect the soil.

<> the damage of green bugs reaches its peak during the grape leaf development period, so we must pay attention to the prevention and control of green bugs at this time. Spraying is required throughout the vineyard, including the leaves, branches, soil surface and weeds of the grapes. You can choose bifenthrin EC 2000 times liquid + 5% imidacloprid EC 2000 times liquid spray control, or 5% fipronil EC + cypermethrin EC 2000 times liquid spray control, interval 7 10 days and then spray 1 time.

Biological control is to make full use of the natural enemies of grape pests and diseases to achieve the purpose of inhibiting the development of pests and diseases or eliminating pests and diseases. To put it bluntly, it is to treat insects with insects and bacteria with bacteria. This method has the characteristics of being safe for grapes, green and ecological, and does not pollute the environment.

The vineyard should be cleaned and disinfected, and when appropriate, the diseased branches and residual branches should be removed in time through pruning, the old bark should be scraped off in time, and the diseased branches and residual leaves should be concentrated for treatment. No matter how good the medicine is, it is not used in the critical prevention and treatment period, and the effect is average. Be sure to remember:

Different varieties have different emphasis on the occurrence of pests and diseases, and the open air and protected areas are also different, and there are also differences between the north and the south of the same species.

It will make the young grape leaves malnourished, and it will also dry up the young grape leaves, and it will attract a lot of insects. The control method is to effectively remove the surrounding weeds, control the use of fertilizer, and use avermectin for control.

Damage to new shoots: It is easy to have poor growth, dryness and shrinkage. Young leaves are damaged:

First, there are reddish dead dots, and then as the leaves grow, the dots will turn into irregular holes, commonly known as "leaf breaking madness". Flower bud damage: It is easy to dry up and fall off due to poor growth.

Damage to young fruits: Brown dots appear at first, and then as the young fruits grow, the dots will turn into black brown spots, and even cause cracking of the young fruits. The internal and external enveloping method is used to administer the drug.

First spray the periphery of the orchard, seal its way out, and then spray the inside of the orchard to achieve the encirclement of the whole garden. It is best to choose the afternoon on a sunny day. Medication after rain.

The grape green blind bug is suitable for living in an environment with a relative humidity of about 80, and excessive rainfall in the open air and humid environment in greenhouses are conducive to breeding. Especially in areas with too much rain this year, it is best to have prevention and control measures after each rainfall. Capture the key control nodes during the leaf-opening period and before and after flowering.

Grape green blind bugs are extremely harmful to flowers, so the use of drugs before and after flowering is a critical period for the prevention and control of grape green blind bugs.

The adults and nymphs of the grape green blind bug live by sucking the juice of grapes, and the adults and nymphs of the green blind bug will suck the young shoots, young leaves, flower buds, fruits, etc. of the grape, and the new shoots of the grape become dry after being sucked: the young leaves are damaged and shrunken, deformed and perforated; After the flower bud is damaged, it stops developing and withers and falls off, the damaged young fruit is deformed, the initial surface presents irregular black spots, as the fruit expands, the black spots turn brown and black-brown, forming irregular scabs, and a few fruits crack at the scabs. Prevention and control measures.

1 Agricultural control.

1) Do a good job of clearing the garden. In early spring, remove weeds from the ground, orchards, and ditches in a timely manner, and bury or burn them deeply. Avoid intercropping leafy greens and straight-root vegetables in the vineyard.

2) In the rainy season, pay attention to ditching and drainage, cultivating and weeding, and reduce the humidity in the park.

3) Do a good job in management (wiping buds, secondary tip treatment, vine binding), and improve the ventilation and light transmission conditions of the shelf.

4) For young trees and overgrown trees, avoid excessive winter pruning and apply more phosphorus and potassium fertilizers to control the amount of nitrogen fertilizer and prevent grapes from growing.

2 Physical control.

During the grape growing season, traps such as insect traps, sticky insect boards and insecticidal lamps can be hung. Studies have shown that in table vineyards, beige and yellow sticky insect boards have the best effect in trapping green blind bugs.

In the vineyards, hanging green and cyan sticky insect boards is the best for trapping. Insecticidal lamps generally use black light.

The prevention and control of green blind bugs should be done: frequently remove weeds inside and outside the park to eliminate the source of insects. After the grape leaves are revealed, nymphs are found to be infested, and they should be sprayed immediately for prevention and control, generally 2500 times of cyhalothrin EC, or 2000 times of 10% cyhalothrin EC.

Many green blind bugs live on weeds in the field, and all of them should be sprayed when spraying pesticides to effectively control the harm of green blind bugs.

For the culture soil with unsuitable pH, the following measures can be used to adjust. If the acidity is too high, a small amount of lime powder can be added to the potting soil; If the alkalinity is too high, a small amount of sulfur powder can be added to the potting soil.

Green blind bugs occur in April, and imidacloprid is used for prevention and control in mid-April, once a week, three times in a row.

How should green blind bugs be controlled?

<> grape green bugs can be controlled with chlorofluorine, imidacloprid and methyl parathion, the green blind bugs mainly have a very high insect rate after rainfall, which will damage the leaves and fruits of grapes, and will lead to a serious reduction in grape yield. The control of green blind bugs should be carried out as soon as possible, and the spraying of infiltrating drugs should be carried out in the afternoon on a sunny day, and it needs to be controlled in time after the rain.

The green bug is an omnivorous pest that uses adults and nymphs to suck the juice of young grape organs through its stinging mouthparts. It is recommended to use 15% chlorofluorine imidacloprid 1500 times for spraying, and 50% methyl parathion 1500 times for control, and the effect on green blind bugs is very obvious.

Green bugs are most suitable to live in an environment with a relative humidity of about 80%, so the insect incidence is highest after rainfall and when the greenhouse environment is humid. In addition, grapes are generally grown in greenhouses, and it is easy to suffer from green blind bugs if you do not take precautions in advance.

The green bug mainly harms the leaves and fruits of the plant, it will gnaw on the juice of the leaves, causing small red dots on the leaves, and the leaves will tear when they grow, and at the same time will gnaw on the juice of the grape fruits, which will inhibit the growth of the fruits, and if not treated in time, it will lead to a serious reduction in grape yields.

Here are the tips for controlling green blind bugs, which can help us achieve twice the result with half the effort. First of all, the prevention and control should be early, and the spitting period is the hatching period of grape green blind bug eggs, which is the best period for control. When taking medicine, you should choose a sunny afternoon, and spray the drug in time after the rain for prevention.

Summary. Grape seedlings can still survive after being infeted with green blind pythons, but they may be affected to a certain extent, such as stunted growth and reduced resistance.

Summary. Hello dear, it's hard to regenerate. If the seedlings have been severely damaged by the green bugs, their ability to regenerate will be greatly reduced.

The green bug is a pest that sucks the juice of plants, and its long-term activity can lead to the loss of nutrients and water from the grape seedlings, thus affecting their normal growth and development. Even under ** and protective measures, the vines may not be able to fully return to their original state of health. Therefore, avoiding the attack of green bugs is the best way to protect the growth of grape seedlings.

Hello dear, it's hard to regenerate. If the seedlings have been severely damaged by the green bugs, their ability to regenerate will be greatly reduced. The long-term activity of the green blind bug Cahu is a pest that sucks the sap of the grape and feasts, and its long-term activity can lead to the loss of nutrients and water from the grape seedlings, thus affecting their normal growth and development.

Even under ** and conservation measures, it is possible that the vine seedlings will not be able to fully return to their original state of health. Therefore, avoiding the attack of green bugs is the best way to protect the growth of grape seedlings.

Here's how to prevent green blind bugs on grape seedlings:1Regular Patrols:

Detect Xiangtan green blind bugs in time and take measures to prevent and control them. 2.Pharmaceutical prevention and control:

Professional pesticide spraying or soaking treatment is used, but the dosage and mu safety should be paid attention to when using. 3.Diversified planting:

Instead of monocropping, you can choose to plant other plants around the grapes to attract green bugs to control green bugs. 4.Maintain the environmental hygiene of the orchard:

Remove leaves and dead grass regularly to reduce the number of places where the insects can hide. 5.Strengthen water and fertilizer management:

Maintain sufficient nutrients and soil moisture to enhance the ability of the grape seedlings to resist green bugs. In short, the combination of the above preventive measures can effectively protect grape seedlings and reduce the harm of green blind bugs.

Summary. Hello dear! Glad for your question.

Grape seedlings can regenerate after being infested with green bugs. Pests of green bugs can regenerate by natural reproduction, but this process takes some time. In addition, grape seedlings can also speed up their regeneration through manual control, such as the use of chemical control, biological control and other technologies to control their reproduction, so as to achieve the purpose of controlling them.

After the grape seedlings get green blind spring, can the grape seedlings still live?

Hello dear, after the grape seedlings get green blind spring, whether they can survive depends on the severity of the disease. If the disease is not severe, the seedlings can survive, but they need to be carried out in a timely and effective manner. In general, the following measures can be taken to ** green blind spring:

1. Timely fertilization and replenishment of nutrients; 2. Weeding in time to keep the environment around the grape seedlings clean; 3. Prevent and control diseases in time to avoid the occurrence and spread of diseases; 4. Apply effective plant growth regulators in time to promote the growth and development of grape seedlings. In addition, plant resistance breeding can be used to breed disease-resistant grape varieties to prevent the occurrence of green-blind springs.

Do you want to remove the leaves that have been eaten by insects.

Dear, Jian Zhengyan suggested that you should remove the leaves that have been eaten by insects, so as not to affect the growth and development of grape seedlings. Because the leaves that have been eaten by insects can cause malnutrition of the grape seedlings, which affects their growth and development. In addition, the leaves that have been eaten by insects can also breed pathogens, which is extremely detrimental to the healthy development of the grape seedlings.

Did I spray dinotefuran?

Dear, it is not recommended to spray dinotefuran to prevent green blindness, because dinotefuran is a toxic pesticide that, if not used properly, may cause harm to grape seedlings and even human health. The prevention and control methods are: 1. Weeding in time, keeping the vineyard clean and reducing the breeding of germs; 2. Timely fertilization to enhance the disease resistance of plants; 3. Timely pest removal to control the breeding of pests; 4. Spray pesticides in a timely manner, and use pesticides with low toxicity and low residues, such as deltamethrin, cypermethrin, etc.; 5. Do a good job of plant pruning in time to promote the normal growth of plants; 6. Do a good job of plant protection in time, such as drought resistance, cold resistance, heat resistance, wind resistance, etc.; 7. Do a good job in the prevention and control of plant diseases in a timely manner, such as anti-bacteria, anti-fungal, anti-virus, etc.
